How C02 is structured
The Arrhythmology Devices branch runs 3 levels deep. 7 entries below are branch headings that group other codes rather than naming a device, so a classification has to resolve all the way down to one of the 31 codes marked terminal.
8 terminal codes are “- Other” entries and 5 are “- Accessories” entries, 42% of the branch. An “- Other” code is the residual slot for devices its siblings do not name, so it is worth ruling out every specific sibling before settling on one.
The largest sub-branch is C0201 (Cardiac Electrophysiology and Mapping Devices), holding 10 of the 31 terminal codes.
Frequently asked questions
- Which C02 codes can be used in a EUDAMED device record?
- 31 of the 38 codes listed under C02 (Arrhythmology Devices) are terminal and can be selected. The other 7 are branch headings that cannot.
- How deep is the C02 hierarchy?
- The C02 branch runs 3 levels below the group code. Its largest sub-branch is C0201 (Cardiac Electrophysiology and Mapping Devices), which holds 10 of the 31 terminal codes.
- How many C02 codes are catch-all entries?
- 8 terminal codes under C02 are "- Other" entries and 5 are "- Accessories" entries, 42% of the branch. The remaining 18 name a specific device type.
